Abstract The reaction of nickel(II) acetylacetonate trimer with 1,3-bis(2,4,6-trimethylphenyl)imidazolium chloride, [IMesH]Cl, leads to the formation of the remarkable double salt 11MesHJANiC141.11Me5HICI 2. (or alternatively [IMesH](3)[NiCl4]Cl). The solid-state structure of this species was determined by a single X-ray diffraction study. The molecular parameters of the ions are unremarkable, but this double salt crystallizes in the chiral space group P6(3) despite the achiral nature of all the ions: the chirality arises from the helical arrangement of the imidazolium mesityl groups. Additionally, the crystal contains hydrophobic channels of ca. 4.5 angstrom diameter, and there are extensive H-bonding interactions in the crystal. The double salt reacts with potassium tert-butoxide to give the known bis-N-heterocyclic carbene complex trans(Ni(IMes)(2)Cl-2], 3. (C) 2014 Elsevier Ltd. All rights reserved.
